BURNER FOR- GAS STOVES AND RANGES.

Application filed September 28, 1928. Serial No. 665,361.

T 0 all whom it may concerm'.

Be it known that I, CLARENCE V. R03- ERTS, a citizen of the UnitedStates, residing in Philadelphia, Pennsylvania, have invented certainImprovements in Burners for Gas Stoves and Ranges, of vwhichthefollowing is a specification.

My invention relates to certain improvements in burners for gas stovesand ranges.

The object of the invention is to construct the burner so that it can belocated close to the edge of the stove, or range, and to provide amixing chamber of such length that the air and gas will bemixedthoroughly before entering the burner.

In the accompanying drawings:

Fig. 1 is a plan view, partly in section, illustrating my improved gasburner;

ig. 2 is a longitudinal sectional view on tln line 22, Fig. 1;

Fig. 3 is a transverse sectional view on the line 33, Fig. 1; and

Fig. 4 is an inverted, sectional plan View of the burner.

vReferring to the drawings, 1 is the body of the burner, made in asingle casting, having arms 2 radiating therefrom in the manner shown inFig. 1. The body and arms of the burner are hollow, as shown. In theupper surface of the body and arms are a series of small perforations3-for the escape of gas. At the center of the burner is an opening 4 forthe passage of air to aid combustion. Depending from the two side armsare feet 5, in the present instance, which rest upon a suitable supportand retain the burner in position.

6 designates a mixing chamber, extending from the center of the body 1of the burner to a point beyond the front of the stove, or

range, as shown by a dotted line 7 in Fig. 0 The end of the mixingchamber is enlarged, as at 9. This enlarged portion, usulil ally, islocated on the outside of the body of the stove, as shown. At the end ofthe chamber is a central opening 10 for agas pipe 8., which is shown bydotted lines. Around the opening are air inlet passages 11 that areclosed by a valve 12, which can be turned to control the amount of airentering the mixing chamber.

Generally, the mixing chamber is connected to the front arm of theburner. When the burner is arranged close to the edge of a'stove, orrange, the mixing chamber is short, consequently, the air and gas arenot mixed thoroughly.

By my invention, however, the mixing chamber is extended under theburner, as shown in Fig. 4, and the inner end is bifurcated, as at 13,to pass on each side of the central opening 4. Short passages 14 formcommunication between 'the mixing chamber and the interior of theburner.

By this construction, the burner can be placed close to the edge of thestove, or range, yet the mixing chamber willbe of sulficient length toallow the air and gas to be mixed properly before entering the burner.

Furthermore, by separating the mixture and allowing it to enter theburner at two points, a better distribution of gas is attained.

I claim:

The combination in a gas burner, of a hollow integral casting forming abody portion having a central opening for air; perforated, hollow armsprojecting radially from the body portion; a longitudinal mixing chamberextending under the burner and bifurcated at its inner end to pass oneach side of the central air opening, the ends of the bifurcatedportions .of the mixing chamber communicating with the hollow body.portion of the burner; and means for admitting gas and air to themixing chamber.

CLARENCE v; ROBERTS.
